Example 4. Four colours of slabs

The patio needs 240 slabs.

Denzel wants a quarter (¼) of the slabs to be sandstone, a quarter (¼) to be slate grey, a quarter (¼) to be terracotta and a quarter (¼) to be golden sunset.

To calculate a quarter (¼) of any number, share it by 4.

Set the sum out like this:

Patio area | Shaped slabs | Two colours of slabs | Four colours of slabs |
Bird tally | Shaped planters | Garden lights | Wiring problems
